Spring Boot Knowledge Patch

Check the relevant topic reference before changing applications, libraries, starters, build plugins, tests, container images, or operational configuration. Do not rely on older package names, defaults, property keys, or extension points.

Working method

1. Identify the affected layer: build/runtime, configuration, web, data, security, observability, testing, local infrastructure, or Spring AI.
2. Read the matching reference file from the index. Read more than one when a change crosses layers, such as an HTTP client carrying OAuth credentials or a data client using an SSL bundle.
3. Apply removals and renamed properties before adding features. Old compatibility paths often no longer exist.
4. Re-check defaults that affect exposure, redirects, proxy trust, serialization, bean selection, context propagation, or resource loading.
5. Keep version-sensitive workarounds only when the reference explicitly limits them to a particular release.
